Definitions
- an unsaturated aldehyde or ketone comprising reacting an olefine containing at least three carbon atoms with a mercuric salt and oxygen is an 3,471 ,566 Patented Oct. 7, 1969 acidic aqueous medium in the presence of a metal catalyst as hereinbefore defined.
- Example 1 illustrates the preparation of a palladium catalyst
- Examples 2 and 3 illustrate one aspect of the invention namely the oxidation of mercurous salts to mercuric salts.
- Example 4 illustrates the concurrent oxidation of mercurous salt to mercuric salt and of olefine to aldehyde.
- Examples 5 and 6 illustrate the use of silver and platinum respectively as the catalyst metal in the oxidation of mercurous sulphate.
- EXAMPLE 5 A catalyst consisting of finely divided silver supported on silica gel and containing 5% by weight of silver was prepared and 1 g. of it mixed with 0.15 g. mercurous sulphate in 50 ml. of N sulphuric acid. The mixture was heated to 90 C. and oxidised for 60 minutes with a current of air passed through at the rate of 25 litres/hour. Some of the mercurous sulphate was oxidised to mercuric sulphate.
